FASTENERFOR THE MEETING-RAILS OF SASHES."

SPECIFICATION forming part of Letters Patent No. 381,113, dated April 17 1888 Application filed December 23, 1887. Serial No. 258.83 (ModeLl To aZZ whom, it may concern-.-

Beit known that I, OSBORN R. COOKE, of Salem, in the county of Golumbiana and State of Ohio, have invented certain new and useful Improvements in YVindow Fasteners or Buttons; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

My invention relates to an improvement in sash-fasteners, the object of the same being to provide a sash-fastener that cannot be unlocked byintroducing any instrumentfrom the outside between the meeting-rails; that will as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of a fastener applied tothe meeting-rails of the sashes. Fig. 2 is a plan view'showing the. two sections lgcked. Fig. 3. is a similar view showing them unlocked. Fig. t'is an endview of the fastener, and Fig. 5 shows. the several parts of the fastener detached.

A represents an arched plate terminating atits side edges in fiatwings orproj ections a, in which are formed screw-holes a for the passage of the screws which secure the plate to the meeting-rail of the lowersash. The plate A is open at its outer end for the passage of the bolt B, and the under surface of the arched portion thereof is concaved to form a halfbearing for the bolt B, which latter, as WliLbe hereinafter explained, has a rotary anda lonpoint at or to one side ofthe vertical center of v arched portion, and forminga bearing for the the arched portion and extending downwardly and inwardly and terminating well tinder said lug d of the bolt B,when the latter is moving 1 in a longitudinal directionto engagetheloolgin'g-plate attached to the uppersash;

A concave-faced or grooved block, 0, is adapted to fit within the arched portion ofthe plate A and forma half-bearing for the bolt B, the latter fitting snugly between the grooved face of the block and the under-surfaces of the f arched portion of the plate A. This block is provided on its sides with flangese, which latter rest in recessesformed on the lower face of "the plate A and prevent displacement of the block when the plate A is secured to a sash.

To still further connect; the block to plate A to prevent displacementwhile assembling the parts and after they have been assembled, I

provide the flanges c with pins or projections e, which latter passv upwardly through holes 6 formed'in the projections a of the plate A, 1 i f and are upset at their freeends, thus securely locking the parts together. The block C is also provided with an inclined bearing-face, f,

which latter, when the block and plate A are in proper relative position, rests under and concentric with the inclined surface c of "the plate A, the space between the two inclined surfaces forming a cam-groove inwhich the lug dofthe bolt Brests while the bolt is being turned and moved longitudinally. Thebolt, 1 B is provided at its free end with a lockingtongue, 9, adapted to engage the locking-plate on the upper sash and lock thetwoparts of the fastener together. I The free end of the bolt immediately behind or on the side opposite the tongue gis cut away or beveled, and when the bolt is slid longitudinally this bev eled portion, which is then uppermost; comes under the top of the locking-plate. This arrangement of parts forms an eccentric or camshaped end, and hence when the'boltisturned," if the plate A and locking-plate be slightly out;

of alignment, the bolt will bear against the bolt B, and is also provided with a lip or rim, h, having an inclined face against which the inclined face of the tongueg of the bolt B bears while the bolt is being turned to a position to lock the parts for the purpose of drawing the meeting-rails of the sashes together.

The lug d on the bolt is set obliquely to the bolt, and during the first portion of the revolution of the bolt to unlock the parts the lug is outside of the groove formed by the block 0 and plate A, and hence there is very little longitudinal movement of the bolt. As soon, however, as the tongue 9 leaves or falls below the rim h of the locking-plate the lug dcomes in contact with the inclined face of the block 0 and the bolt is withdrawn from the lockingplate. By turning the bolt in the opposite direction the lug d bears against theinclined face on the under side of the arched portion of the plate and moves the bolt toward and into the locking-plate. The bolt is turned by the lever H, preferably cast integral with the bolt. This lever, when the tongue 9 has entered the cavity or recess in the locking-plate, rests close up to the end of the arched portion of the plate A, and to assist the tongue in drawing the meeting-rails of the sashes together I have formed an incline, i, on the end of the arched portion of the plate, against which the lever 11 bears when the latter is turned in direction to lock the parts.

From the foregoing it will be seen that the entire fastener is made up of four simple parts, which when combined form a neat and compact device that cannot get out of order, or the parts thereof displaced. These parts, which are cast, requirebut little finishing, and no experience whatever is required to enable themto be properly assembled and applied to a window.

While I have shown the locking-plate as slotted, it is evident that the slot can be dispensed with, as the rim hon the under side is all that is required. Again, it is evident that the plate A can be secured to the upper sash and the locking-plate to the lower sash, and that other slight changes and alterations might be resorted to without departing from the spirit of my invention; hence I would have it understood that I do not confine myself to the a I exact details of construction herein described,

but consider myself at liberty to make such changes and alterations as fairly fall within the spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with an arched plate having an inclined face, and a bearing-block located within the arched portion of said plate and having an inclined face, of a bolt having a lug adapted to rest and move between said inclined faces, substantially as set forth.

2. The combination, with an arched plate having an inclined face,a bearing-blocklocated within the arched portion of said plate and having an inclined face, and a lockingplate provided with a depending rim, the latter having an inclined face, of a bolt having a lug adapted to rest and move between said inclined faces, and a tongue adapted to engage the inclined face of the rim.

3. The combination, with an arched plate, a bearing-block, a locking-plate, and a rotary andlongitudinally-sliding boltlocatedbetween the arched plate and bearing-block and provided with a lug adapted to engage inclined faces on the plate and block, and with a tongue for engaging a rim on the locking-plate, of a handle secured to the bolt and adapted to engage an inclined surface on the arched plate for drawing the meeting-rails of the sashes to- OSBORN R. COOKE.
